Danfoss FCM 300 Series Design Manual page 4

All operations must be carried out by
appropriately trained personel.
Use all lifting facilities provided e.g. both lifting points
if fitted or single lifting point if fitted*.
Vertical lifting - Prevent uncontrolled rotation.
Lift machine - Do not lift other equipment with motor
lifting points only.
Before installation check for fan cover damage, shaft
damage, foot/mounting damage, and loose fasteners.
Check nameplate details.
Ensure level mounting surface, balanced mounting,
not misaligned.
Gaskets, and/or sealants, and guards must be
correctly fitted.
Correct belt tension.
Please observe derating rules, see "Special
conditions".
*Note: maximum hand lift is 20 kg below
shoulder, but above ground level. Max.
gross weights:
- Frame size 80: 15 kg
- Frame size 90 & 100: 30 kg
- Frame size 112: 45 kg
- Frame size 132: 80 kg
The voltage on the FC motor is
dangerous when the motor is connected
to mains. Incorrect installation of the FC
motor may lead to material damage or serious injury,
or it may be fatal.
Consequently, the instructions in this manual as well
as national and local rules and safety regulations
must be complied with.
Touching the electrical parts may be fatal, even after
the mains supply has been disconnected.
Wait at least 4 minutes.
- Installation must be fused and isolated correctly.
- Covers and cable entries must be fitted.

NB!
It is the user's or certified electrician's
responsibility to ensure correct earthing and
protection in accordance with applicable national and
local requirements and standards.
Safety regulations
1. The VLT ® DriveMotor (FC motor) must be
disconnected from mains if repair work is to be
carried out.
Check that the mains supply has been
disconnected and that the necessary time has
passed (4 minutes).
2. Correct protective earthing of the equipment
must be established, the user must be
protected against supply voltage, and the motor
must be protected against overload in
accordance with applicable national and local
regulations.
Use of RCD's (ELCB relays) is described in
chapter 10.
3. The earth leakage currents are higher than
3.5 mA. This means that the FC motor requires
a fixed, permanent installation as well as
reinforced protective earthing.
Warning against unintended start
1. The motor can be brought to a stop by means of
digital commands, bus commands, or
references, while the frequency converter is
connected to mains.
If personal safety considerations make it
necessary to ensure that no unintended start
occurs, these stop functions are not sufficient.
2. While parameters are being changed, the motor
may start.
3. A motor that has been stopped may start if
faults occur in the electronics of the FC motor, or if a
temporary overload or a fault in the mains supply
ceases.
